Cristiano Ronaldo’s Portugal will face Poland on Thursday night in the first quarterfinals of the Euro 2016. Portugal was lucky to escape Croatia by a solitary goal in extra time in the round of 16.

Injury concerns have left Portugal coach Fernando Santos’ final selection of the starting lineup in jeopardy. Santos will make the final decision at the last possible minute due to injuries to two key players.

Defender Raphael Guerreiro and midfielder Andre Gomes may miss the quarterfinal tie. Both the players haven’t trained with the team on Monday and were missing on the pitch on Wednesday.

Poland scraped into the last eight stage by winning 5-4 in the penalty shoot-out against Switzerland in the second round encounter. The regulation time dished out a 1-1 draw.

Both the teams look strong on paper, but Cristiano Ronaldo and company hasn’t won a single game in 90 minutes in this edition of the tournament so far.

Ronaldo on his day could destroy any team and Polish coach will deploy Michal Pazdan to mark his footsteps from the beginning of the game. The Real Madrid superstar was on song and led a furious assault in the 3-3 draw against Hungary in the group stage, which is probably the game of this European championship so far.

“It is what Cristiano is all about,” said Fernando Santos, according to the Independent. “He had to score those goals because he is a winner.”

Poland will bank on Bayern Munich’s star striker Robert Lewandowsky to notch up a winner. The Polish defense finished their Group C outings without conceding a single goal.
